Abstract
본 발명은 카메라나 프로젝션 텔레비젼 등에 적용되는 광학계의 광량 조절장치에 관한 것으로서, 특히 주위 빛의 세기에 따라 빛의 입사량을 가감하도록 조절하는 조리개를 포함하는 광학계에 있어서, 상기 조리개는 일정한 구경을 유지하고 주위 빛의 세기에 따라 위치를 이동시키는 이송수단의 작동에 의해 빛의 입사량이 조절되는 것을 특징으로 한다.The present invention relates to an optical system for adjusting the amount of light of an optical system applied to a camera, projection television, and the like, and more particularly to an optical system including a diaphragm for adjusting an incident amount of light according to the intensity of ambient light, And the incident amount of light is adjusted by the operation of the conveying means for moving the position according to the intensity of the ambient light.
따라서, 본 발명에서는 조리개의 위치에 따라 광량의 조절이 가능케됨으로써 광량의 조절이 정확하게 이루어짐과 동시에 용이하게되고, 특히 통공의 형상에 따라 개구량을 조절할 수 있으므로 카메라 뿐만 아니라 3개의 음극선관을 채택한 프로젝션 텔레비젼에서는 좌우의 적, 청색에 대한 세이딩(Shading) 현상의 발생을 최소화 할 수 있는 등의 여러가지 효과가 있다.Therefore, according to the present invention, the amount of light can be adjusted according to the position of the diaphragm, so that the amount of light can be precisely adjusted and facilitated. In particular, since the opening amount can be adjusted according to the shape of the through- In TV, there are various effects such as minimization of occurrence of shading phenomenon with respect to left and right red and blue.
